Lineage-specific variation in the evolutionary stability of coral photosymbiosis The evolutionary stability of photosymbiosis differs among lineages of reef-building corals.

... to reconstruct the evolutionary history of the trait, it was found that photosymbiosis is a remarkably stable trait, rarely showing evidence of reversion to a non-symbiotic lifestyle even among corals that acquire symbionts from the environment each generation (doi.org/10.1126/scia...) ..

A picture of our group member Jordan Gault, taken in the caste in Copenhagen. You can see a bearded man with glasses standing in a grand, ornately decorated hallway with a checkered marble floor. He has dark brown hair and is smiling. He is wearing a flat cap, blue vest over a shirt, dark trousers, and a dark jacket with one hand in his pocket. Behind him, the hallway is lined with large, colorful tapestries and elegant furniture, leading to a distant area with a red throne-like seat. The lighting is warm and soft, giving the scene a historic and majestic ambiance. And yes, he looks like a mixture of an oldtimey academic and a wizard (in a good way).
